Definitely keeping my phosphates in check and my slight bit of algae I have is starting to die off. Well worth the price and great value!

Phosphates at ZERO!By Michael on 12/6/2010

Michael would recommend this product to a friend

I bought this product because no matter what I did my phosphates would stay about .5ppm. I use it in a phosphate reactor and my levels have been at 0.0ppm since then. I would recommend this to everyone with a phosphate problem.
